[PATCH] server: Print a warning if home and config directories are equal.

[Bernhard Übelacker]

Signed-off-by: Bernhard Übelacker

I observed today the comdlg32:itemdlg test failing because it could
not find c:/home/user/Desktop, which itself is a link to $HOME,
which got ignored because $HOME and $WINEPREFIX were the same.
Maybe a warning like could help to avoid such a misconfiguration.
